Final answer:
The process of hand blending involves freezing the ingredients and then blending them in a blender. Alternatively, the mixture can be placed in a plastic bag surrounded by ice and shaken to churn the ice cream while cooling it.
Step-by-step explanation:
The process of hand blending involves freezing the ingredients and then blending them in a blender. This can be done by placing the ingredients in a container that is freezer-safe and stirring the mixture vigorously every 45 minutes for several hours to prevent it from turning into a solid block of ice. Another method is to place the mixture in a plastic bag surrounded by ice and shaking it for five minutes to churn the ice cream while cooling it evenly.
